[0050] It is worth noting that see Figure 4 The first alcohol content detector 13 and the second alcohol content detector 23 are electrically connected to the data storage unit and the comparison unit through wires respectively. The infrared detection sensor is installed at the door frame of the main driving cab of the vehicle, and its detection end is vertically downward. The infrared detection sensor is electrically connected to the vehicle control system. The vehicle control system and the alcohol detection system are electrically connected to the vehicle battery through wires. The vehicle battery supplies power to the entire circuit. The infrared detection sensor will detect when the driver enters the main driving cab, and the infrared detection sensor will transmit the detected information to the vehicle control system so that the vehicle control system can control the alcohol detection system to operate.

[0051] It is worth introducing a vehicle alcohol detection and locking method, the detection steps are as follows;

[0052] S1. When the driver uses the car key to unlock the car, the vehicle control system transmits the received signal to the unlocking unit, which then controls the electronic lock of the main driver's door to open;

[0053] S2. When the electronic lock of the main driver's door is opened, the first electric push rod 11 of the alcohol detection system will drive the first alcohol content detector 13 to move out of the storage box 14, and at the same time, the first air extractor 12 will operate, and the first air extractor 12 will absorb the air in the cab through the first air collecting hood 16 and transport it to the inside of the first alcohol content detector 13 for detection, and then the data storage unit will store the detected data;

[0054] S3. When the driver enters the main cab, the infrared detection sensor transmits the detected information to the vehicle control system, and then the vehicle control system controls the second electric push rod 21 on the alcohol detection system to operate. At this time, the second electric push rod 21 drives the second alcohol content detector 23 to move out from the inside of the installation slot 24. At the same time, the alcohol detection system controls the second alcohol content detector 23 and the second air extractor 22 to operate. At this time, the second air extractor 22 absorbs the air around the neck and head of the driver sitting on the main driving seat 2 of the vehicle through the second air collecting hood 26, and transports the absorbed gas to the second alcohol content detector 23 for detection. The first air extractor 12 will operate again, and the first air extractor 12 will absorb the air in the cab through the first air collecting hood 16. At the same time, the driver pulls out one end of the gooseneck hose 17 from the other side of the first air collecting hood 16 and blows air into it with his mouth. Then the first air extractor 12 transports the air blown by the driver and the gas absorbed in the cab to the inside of the first alcohol content detector 13 for detection;

[0055] S4. The comparison unit then compares the initial data stored in the data storage unit and the alcohol content data of the driver entering the main cab before the test;

[0056] S5. The data feedback unit then transmits the compared data to the vehicle control system. When the alcohol content meets the standard, the vehicle control system will control the electromagnetic switch to be disconnected, so that the ignition switch is powered off, and control the alarm through the alarm unit to sound an alarm to remind the driver. When the alcohol content does not meet the standard, the vehicle control system will control the electromagnetic switch to be closed, so that the ignition switch is powered on to ignite. At the same time, the first electric push rod 11 will drive the first alcohol content detector 13, the first vacuum pump 12 and the first gas collection hood 16 to be stored in the storage box 14, and the second electric push rod 21 will drive the second alcohol content detector 23, the second vacuum pump 22 and the second gas collection hood 26 to be stored in the installation slot 24.

[0057] Specifically, the comparison unit compares the initial data stored in the data storage unit with the alcohol content data detected before the driver enters the main cab. Specifically, the alcohol content detection data before the driver enters the main cab minus the initial alcohol content detection data is used to determine whether the driver has been drinking based on the result.

[0058] Example 2: See Figure 1 and Figure 3The alcohol content detection mechanism also includes a second electric push rod 21, a second air pump 22 and a second alcohol content detector 23, wherein the output end of the second electric push rod 21 is fixedly connected to the bottom end of the second alcohol content detector 23, and the second air pump 22 is fixedly connected to one side of the second alcohol content detector 23, wherein the air outlet end of the second air pump 22 is matched with the air inlet end of the second alcohol content detector 23, and is sealed and connected;

[0059] Further, see Figure 3 The second electric push rod 21, the second air pump 22 and the second alcohol content detector 23 are installed inside the mounting groove 24 of the main driving seat 2 of the vehicle. The top of the mounting groove 24 is movably connected with a second cover plate 25. The bottom end of the second cover plate 25 is fixedly connected to the top of the second alcohol content detector 23. One side of the second air pump 22 is fixedly connected with a second gas collecting hood 26. The vehicle control system controls the second electric push rod 21 on the alcohol detection system to operate. At this time, the second electric push rod 21 drives the second alcohol content detector 23 to move out from the inside of the mounting groove 24. At the same time, the alcohol detection system controls the second alcohol content detector 23 and the second air pump 22 to operate. At this time, the second air pump 22 will absorb the air around the neck and head of the driver sitting on the main driving seat 2 of the vehicle through the second gas collecting hood 26, and transport the absorbed gas to the second alcohol content detector 23 for detection.

[0060] It is particularly noted that rear drive motors and fan blades are installed inside the first air pump 12 and the second air pump 22;

[0061] The alcohol content detector is actually composed of an alcohol gas sensor (equivalent to a variable resistor that changes with the alcohol gas concentration), a fixed value resistor, and a voltmeter or ammeter. Figure 4 The figure shows its principle diagram. In the figure, R1 is a fixed value resistor, and the resistance value of the alcohol gas sensor R2 decreases as the alcohol gas concentration increases. If the alcohol gas concentration exhaled by the driver is higher, the voltage reading of the tester will be higher.
